Holman, Louise Elizabeth
Vocational interest is a dynamic, subjective, positive attraction towards a job, occupa tion or occupational field, based on the individual's perception of the structure of occupations and situations already experienced or expected to produce pleasurable feelings. Interest test tields are usually statistically derived from characteristics of individuals. This study develops and validates an interest test based on the perceived occupationaI structure.
After examining various classification models and occupational classification systems, including work by Holland, Gati and Roe, a new network access model was pro­posed, based on many-to-many correspondence in set theory. Categories are arranged on levels. Choice of a category on one level precludes access to another category on the sanK level, but does not restrict access to categories on other levels. It was hypothesised that occupational structure is perceived to consist of the three levels of lields, environments and duties. Each category is a horizontal sirus group and includes all vertical status levels. Career choice is based on preferences at each level. 1200 jobs have been classified by allocation to one category on each level, and each is described by a field, environment and duty. The field-environment-duty (FED) system was operationalised in a ten minute interest test asking testees to choose from each level the three categories that interest them for a job. Extensive use was made of x to the power of 2 and empty sets to the power of two statistics in analysing nominal measurement scores. The FED test was applied to 1280 school-leavers in Gauteng, South Africa. Research supports Gati's division of occupations into "soft" (people-oriented occupations preferred by females), and "hard" (not-people-oriented occupations preferred by males), and introduces a third "neutral" division which is preferred equally by both males and females. Construct and concurrent validity was shown with the I 9Fll, VIQ, SDS and l6PF. In a four to five year longitudinal study the FED was found to predict future studies (80%) and occupation (86%). Research with working adults found that the FED test predicts concurrent job satisfaction, job tenure and self-assessed performance. Inter-rater reliability in assigning jobs to categories is around 80%. Test-retest reliability was significant to the 0,0001 level using the x to the power of 2 goodness of fit test.

Visser, Chrisna
Hierdie ondersoek handel oor die psigometriese verwantskappe tussen verskeie konseptualiserings van psigologiese optimaliteit. Die konsepte selfaktualisering (vanuit 'n humanistiese raamwerk), gevoel van koherensie en aangeleerde vernuftigheid (vanuit 'n behavioristiese en salutogenesis paradigma) is vir die doeleindes van hierdie ondersoek gekies. Die gekose meetinstrumente, naamlik die Persoonlike Orientasievraelys vir
selfaktualisering, die Lewensorientasievraelys vir gevoel van koherensie en die Selfkontroleskedule vir aangeleerde vernuftigheid, is op 'n steekproef van 200 middelvlakbestuurders in 'n semi-staatsdiensorganisasie afgeneem. Pearsonkorrelasiekoeffisiente is bereken en 'n faktorontleding is gedoen. Daar is verskeie beduidende korrelasies verkry tussen die subskale van die Persoonlike Orientasievraelys en die Lewensorientasievraelys, maar slegs enkele beduidende korrelasies tussen die Persoonlike Orientasievraelys en die Selfkontroleskedule. Die Lewensorientasievraelys en die Selfkontroleskedule het egter beduidend gekorreleer. Die faktorontleding het getoon dat selfaktualisering aan die een kant, en gevoel van koherensie en aangeleerde vernuftigheid aan die ander kant as twee verskillende konstrukte van psigologiese optimaliteit beskou kan word.; The relationships between various conceptualisations of psychological optimisation are investigated. The concepts of self-actualisation (from a humanistic paradigm), sense of coherence and learned resourcefulness (from a salutogenesis paradigm) are relevant. The measuring instruments were the Personal Orientation Inventory (POl), the Orientation to Life Questionnaire (OLQ) and the Self Control Schedule (SCS). They were administered by means of random sampling of 200 middle level managers in a semi-government organisation. Pearson correlation coefficients were calculated and a factor analysis was done. Several significant correlations were obtained between the subscales of the POl and the OLQ, but limited correlations were found between the POl and the SCS. However, significant correlations between the OLQ and the SCS were apparent. The factor
analysis demonstrated that self-actualisation on the one hand and sense of coherence as well as learned resourcefulness on the other hand may be regarded as two seperate constructs of psychological optimisation.

Schulz, Georg Martin
A survey of literature has revealed that there is a need for a reliability and validity study of the Personal Orientation
Inventory in South Africa. The two major objectives of this research where therefore to determine firstly, the test-retest reliability of the Personal Orientation Inventory and secondly, to establish the construct validity, in other words, how well the Personal Orientation Inventory correlates with other measures purporting to measure similar traits. The total sample of 317 individuals used in this research, consisted of both male and female school leavers such as students and national servicemen, ranging in age from 17 to 22 years. The results of this introductory study regarding reliability and validity of the Personal Orientation Inventory in South Africa demonstrated clear support for similar research done overseas and showed to be compatible with the humanistic psychology movement's original concept of self-actualization.

Scholtz, Dewald Toerien
Die doel van hierdie ondersoek is om die verskil in effek tussen direktiewe en nie-direktiewe insette van die fasiliteerder, tydens sensitiwiteitopleiding, te bepaal deur sommige kliente voor te berei op die ervaring deur middel van 'n uitdeelstuk en ander kliente nie voor te berei nie. Die sensitiwiteitgroepe word deurgaans op ongestruktureerde wyse hanteer en met behulp van 'n kwantitatiewe meting en verwerking met t-toetse asook 'n
kwalitatiewe meting word hipoteses getoets. Die instrumente wat gebruik word is die POI, Rotter, Firo-B en 'n oopvraag-tegniek. Die resultate dui daarop dat persone wat voorberei word op die ervaring 'n groter interne lokus van kontrole openbaar.; The aim of this study is to determine the difference in effect between directive and non-directive inputs by the facilitator during sensitivity training, by preparing some clients for the experience with the aid of a handout while other clients go through the same experience unprepared. The sensitivity groups are run on an unstructured basis and effects are measured with a quantatitive measurement and calculated with t-tests as well as
qualitative. measurement, thereby testing the hypotheses. The instruments that are used are the POI, Rotter, Firo-B and an open question technique. The results seem to indicate that people who are prepared for the experience show a higher internal locus of control.
